摘要:
Disclosed is a composition for a silica-based insulation layer including hydrogenated polysilazane or hydrogenated polysiloxzane, wherein a concentration of a cyclic compound having a weight average molecular weight of less than 400 is less than or equal to 1,200 ppm. The composition for a silica-based insulation layer may reduce a thickness distribution during formation of a silica-based insulation layer, and thereby film defects after chemical mechanical polishing (CMP) during a semiconductor manufacturing process may be reduced.
摘要:
Disclosed is modified hydrogenated polysiloxazane prepared by reacting hydrogenated polysiloxazane with a silane compound selected from polysilane, polycyclosilane, and a silane oligomer. The modified hydrogenated polysiloxazane has a small mole ratio of nitrogen atoms relative to silicon atoms and may remarkably deteriorate a film shrinkage ratio when included in a composition for forming a silica-based insulation layer to form a silica-based insulation layer.

摘要:
Provided is a rinse solution for a hydrogenated polysiloxazane thin film including an additive selected from an alcohol-based solvent, an ester-based solvent, a silanol-based solvent, an alkoxysilane-based solvent, an alkylsilazane-based solvent, and a combination thereof in an amount of 0.01 wt % to 7 wt % based on the total amount of the rinse solution.
